Lead System Safety Engineer

Gravitics•Houston, FL

About The Position

Gravitics is seeking an experienced Lead System Safety Engineer to own system safety for their pressurized spacecraft and modular orbital structures. This includes vehicles that approach, berth to, and operate attached to crewed space stations. The role requires earning safety approval through station operator and NASA visiting-vehicle safety review processes. The Lead System Safety Engineer will manage the end-to-end system safety lifecycle, integrating hazard analyses into the design, authoring safety data packages, and representing the company in safety review panels. This position involves providing independent safety assessments and collaborating with various engineering teams.

Requirements

Bachelor's degree in aerospace, Mechanical, Electrical, Systems Engineering, or a closely related technical discipline.
7+ years in aerospace system safety, systems engineering, or propulsion/fluid systems engineering.
Direct authorship of hazard reports or safety data packages approved by NASA for a human-rated vehicle, ISS visiting vehicle (COTS/CRS), or other crewed program.
Hands-on experience with hazard reports, fault tree analysis, and FMECA.
Experience with demonstrating fault tolerance and inhibit schemes for catastrophic hazards.
Working knowledge of SSP 50808 (ISS visiting vehicle requirements), SSP 30599 (safety review process), SSP 30309 (safety analysis and risk assessment), NPR 8715.3 (NASA safety program), and NPR 8705.2 (human-rating requirements).
Technical understanding of pressure vessels and pressurized systems, leak paths, propellant systems (hypergolic and/or green propellants), and battery safety (JSC 20793).
Comfortable navigating technical ambiguity and balancing engineering rigor with rapid manufacturing and test cadences.
Must be a U.S. citizen, lawful permanent resident, or protected individual to comply with U.S. export regulations (ITAR/EAR).

Nice To Haves

Prior presentations before the ISS Safety Review Panel or a commercial station operator safety board.
Proximity operations and berthing safety: relative navigation, automated abort, hold, and retreat logic, collision avoidance, and berthing mechanisms or robotic capture interfaces.
Software safety under NASA-STD-8739.8, including safety-critical flight software and fault-protection logic.
Crew-accessible pressurized volumes: ECLSS, cabin atmosphere monitoring, fire detection, and hatch/ingress safety.
Orbital debris assessment and controlled re-entry/disposal casualty analysis (NASA-STD-8719.14).
Range safety and FAA AST commercial launch licensing.
Requirements and configuration tools such as Jama, DOORS, Jira, or Confluence.
Advanced degree with focus on system safety, risk, or reliability engineering.

Responsibilities

Author and maintain the System Safety Program Plan (SSPP).
Own the hazard analysis baselines, hazard tracking, and safety verification tracking log through closure.
Own the technical relationship with station operator and NASA safety review panels.
Prepare, present, and close the phased (Phase 0/I, II, and III) safety data packages per SSP 30599 and SSP 50808.
Lead preliminary and detailed hazard analyses and author hazard reports with causes, controls, and verifications.
Oversee supporting system-level analyses: Functional Hazard Assessments (FHA), Fault Tree Analyses (FTA) for catastrophic and critical hazards, Failure Modes, Effects, and Criticality Analyses (FMECA) and the Critical Items List, with the reliability team, and operating and support hazard analyses for ground processing, launch-site, and on-orbit operations.
Define safety requirements for, and independently assess, verify, and defend, the two-fault-tolerant (three independent inhibit) architectures required for catastrophic hazards.
Assess the fault detection, isolation, and recovery (FDIR) design developed by systems and avionics engineering, ensuring no single credible failure endangers the host station or its crew.
Bring hazard analysis into open design trades early so safety drives the design.
Flow NASA human-rating and visiting-vehicle safety requirements into verifiable engineering requirements.
Trace hazard controls to verification across hardware, software, and operational procedures in Jama, DOORS, or similar tools.
Work with flight software and software assurance to identify safety-critical software functions and verify abort, hold, retreat, and inhibit logic.
Support range safety data packages (AFSPCMAN 91-710), hazardous ground operations procedures, propellant loading, and launch licensing safety inputs.
Participate in Failure Review Boards.
Assess test anomalies, nonconformance, waivers, and deviations for safety impact, and keep residual risk within human-spaceflight tolerances.
Help build the S&MA safety function as the company grows, including mentoring additional safety engineers.
